Question about Sony XM-752EQX Car Audio Amplifier
I have a Sony XM-752EQX amp that has all of a sudden quit working. I get no sound from the speakers. The unit powers up with the power light coming on. In addition to that the over current, offset, and thermal lights all light up green and flash continually in some sort of a coded pattern. I can't find anything to tell me what the flashing indicates. They all three flash in the same pattern together. Any suggestions as to what is wrong?
Disconnect your subs from the amp. If the lights go out then your sub is blown and is putting the amp into protect. If the lights keep flashing even with the subs disconnected than the Amp is toast.

Sony generally drives their power light from a source that does not rely on the amplifier's switching power supply. This means that it's not a good indicator as to the health of the amplifier.
As long as you have B+ and remote voltage, it will light up. Since you've tested the speaker and the signal source, I think the amplifier is likely defective.
